FWIW, there exist Go libraries that keep the default build phase,
e.g. go-github-com-hashicorp-go-version.  Also, according
to comments in guix/build/go-build-system.scm, it is intended to
someday reuse the compiled build dependencies again (see
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=32919>).

Also, perhaps the 'build' phase is currently largely useless for Go
libraries, I'd expect it to be a no-op in those cases, so I don't
expect it to be necessary to delete the build phase.

I expect that existing instances of (delete 'build) in golang.scm can
be removed, but it's not something I've ever actually tried, so I'm
not sure.
